ROBERTSON, JR., OF MOBILE ALABAMA STEAM PIPE CONNECTION Application filed May 28, 1928, Serial No. 281,305. Renewed November 4, 1930.

This invention relates to a device which may be conveniently referred to as a steam pipe connection, and it has more particular reference to a connection which is especially v designed for providing a leak-proof joint and connection between a steam pipe and smoke box.

More particularly, the invention comprises an air and steam proof connection, where the steampipe enters the smoke box, from the cylinders of a locomotive engine.

Briefly described, the device comprises a tubular outer casing which is welded, brazed, or otherwise rigidly connected with the smoke box, and a steam pipe coupling which fits telescopically within the outer casing, and packing means interposed between and cooperable with these parts to provide a leak-proof oint,

The advantages and features of a structure of this class will be quite clear after considering the following description in conjunction with the drawings.

In the drawings Figure l is aview in section, showing the connection associated with the smoke box.

Fig. 2 is an elevational view of Fig. 1.

Fig. 3 is a perspective view of the tubular casing and packing elements.

Referring now to the drawings by the reference numerals, it will be observed that 4 designates the ordinary smoke box, which is provided in one side with an opening. Extending into this opening, and into the interior of the box is a tubular outer casing 5. This is openended and slit longitudinally to permit expansion and contraction. At its outer end, it is provided with right angular brackets 6 cooperating to accommodate a clamping and retaining bolt 7. On its interior, it is provided with retaining elements for the packing ring 8.

For example, we find here, a pair of inner segmental rigidly mounted retainers 9, and outer semi-circular retainers 10. These are disposed in break-joints or staggered relation, and are spaced apart to receive the packing ring 8 therebetween. The packing ring is shown in assembled relation in Fig. 1.

Cooperating with these parts is the inner steam pipe connection 11. This is provided at its outer end with an apertured attaching flange 12, and the inner end is bent telescopically into the outer section or casing 5. It is therefore adjustable and provides a rigid air and steam-proof connection, which permits a steam plpe from the cylinders of a locomotive, to be properly connected with the smoke box 4.

In fastening the parts 5 to the box 4, I provide a fastening annulus composed of sections 18, these being brazed, welded, or otherwise rigidly connected to the parts 4 and 5 as at 14.

It is thought that by considering the description in connection with the drawings, a clear understanding of the construction and operation of the invention will be had. Consequently, a more lengthy description is regarded unnecessary.

Minor changes in shape, size, and rearrangement of parts coming within the field of invention claimed, may be resorted to if desired.

Having thus described my invention, what I claim' as new is V A steam pipe connector of the class described comprising a tubular section longitudinally slit, and provided adjacent its outer end, and on its exterior with a pair of brackets, a clamping bolt connecting said brackets, retaining elements disposed on the interior of said section, and located adjacent the outer end thereof, a packing ring arranged between said retaining elements, and a steam pipe connecting tube arranged telescopically within said outer section, and cooperable with said packing, said tube being provided at its outer end with an apertured attaching flange for connection with the steam pipe.

In testimony whereof I afiix my signature.

JEROME OWEN ESLAVA.
